I deleted my original Facebook account almost 5 years ago, and this is slightly off topic but I recently made a brand new facebook account just to use marketplace, I gave the bare minimum of information you could give and even used a brand new email address, as soon as I entered my phone number to verify my account I got the creepiest friend recommendations, they must have been pulling them from whatsapp because they were insanely accurate, and that was just with my phone number, with a brand new account and a brand new email.
